By default, presence delivered using the presence event package for
the Session Initiation Protocol (SIP) is represented in the Presence
Information Data Format (PIDF).  A PIDF document contains a set of
elements, each representing a different aspect of the presence being
reported.  When any subset of the elements change, even just a single
element, a new document containing the full set of elements is
delivered.  This memo defines an extension allowing delivery of only
the presence data that has actually changed.  [STANDARDS TRACK]
